The configuration of the hand scanner 130 attached to the shopping cart 10 as viewed from above will be described with reference to FIG. 6. A stacking state of the shopping cart 10 as viewed from the side direction will be described with reference to FIG. 7.

Note that the shopping cart 10 functions as a registration device that reads the product code of a product that a shopper desires to purchase. A list of read products is transferred to a separate device, i.e., a payment device (not shown). Assumption is made that the shopper uses the payment device to which the list of products has been transferred to make payment.

As shown in FIG. 1, the shopping cart 10 according to this embodiment includes a cart body 20 and an electrical device 100. The electrical device 100 is attached to the cart body 20. The cart body 20 transports a shopping basket for housing products. The cart body 20 includes a caster part 30, a frame part 40, and a basket reception part 50. The caster part 30 causes the cart body 20 to smoothly move on the floor surface. The frame part 40 is erected on the rear wheel side of the caster part 30. The basket reception part 50 is attached at the intermediate position in the height direction (vertical direction) of the frame part 40 to protrude toward the forward direction of the shopping cart 10. The caster part 30 and the basket reception part 50 are configured to be capable of appropriately carrying a shopping basket thereon. Note that in this embodiment, the direction in which the basket reception part 50 projects from the frame part 40 (forward direction of the shopping cart 10) is referred to simply as forward or one side of the first direction in some cases as shown in the drawings. Further, in this embodiment, the side of the frame part 40 (rearward direction of the shopping cart 10) is referred to simply as rearward or different side of the first direction in some cases as shown in the drawings. Further, the extending direction of a handle bar 42 described below is referred to simply as width direction or second direction in some cases as shown in the drawings. The above-mentioned first direction and the second direction are, for example, directions orthogonal to each other. Further, the height direction of the shopping cart 10 orthogonal to the horizontal surface including the forward, the rearward, and the width direction of the shopping cart 10 will be referred to simply as vertical direction in some cases as shown in the drawings.

The caster part 30 will be described in more detail. The caster part 30 includes a square frame-shaped frame 31 having a rear side opened, and casters 32 provided at four corners of the frame 31. The casters 32 each include a bracket 32 a and a wheel 32 b. The bracket 32 a freely rotates around an axis in the vertical direction (height direction of the shopping cart 10). The wheel 32 b freely rotates around the horizontal axis of the bracket 32 a. The wheel 32 b is formed of rubber or a resin. Note that a reception part 33 is provided on the frame 31. The reception part 33 is formed in the dimension in which the lower part of the shopping basket is housed. That is, the reception part 33 is configured to be capable of appropriately carrying another shopping basket different from the basket reception part 50 thereon.

The reception part 33 includes a contact part 34 and a regulation plate 35. The contact part 34 is formed at the front end of the reception part 33. When the shopping basket is placed on the reception part 33, the contact part 34 is in contact with the shopping basket to support the shopping basket. The regulation plate 35 is provided rearward of the contact part 34 in the reception part 33. When a plurality of shopping carts 10 is stacked, the regulation plate 35 is in contact with the contact part 34 of the rearward shopping cart 10 to regulate the distance between the shopping carts 10. When the plurality of shopping carts 10 is stacked, the contact part 34 is in contact with the regulation plate 35 formed on the frame 31 of the forward shopping cart 10 to regulate the distance between the shopping carts 10. That is, when plurality of shopping carts 10 is stacked, the regulation plate 35 has a function of regulating the distance with the rearward shopping cart 10, and the contact part 34 has a function of regulating the distance with the forward shopping cart 10. As described above, by regulating the distance between the shopping carts 10, it is possible to prevent, when stacking the shopping carts 10, the hand scanners 130, the tablet cases 140, scanner holders 160, and the like of the forward and rearward shopping carts 10 from being interfered with each other.

Note that the stacking means arranging the plurality of shopping carts 10 in a line along the front-rear direction. Then, as shown in FIG. 7, it represents pushing the front end side of the shopping cart 10 located on the rear side into the rear side of the shopping cart 10 located on the front side, i.e., the side of the frame part 40 for housing. The shopping cart 10 includes a flap plate 54 (described below) provided on the rear side. The flap plate 54 has a structure in which the front end side of the shopping cart 10 located on the rear side is pushed as described above and thus, the flap plate 54 is opened by being pushed up toward a reception unit 52 (described below). Therefore, even in the case where the plurality of shopping carts 10 are arranged, it is possible to shorten the total length along the front-rear direction and improve the efficiency of housing the shopping cart 10.

As shown in FIG. 1, the frame part 40 includes a pair of vertical frames 41 and 41, and the handle bar 42. The vertical frames 41 and 41 are attached on the side of the right and left rear wheels of the caster part 30. The handle bar 42 extends in the width direction, and connects the upper ends (upper end parts in the vertical direction) of the vertical frames 41 and 41. An extension arm 43 is attached to the vertical frame 41 on the left side in FIG. 1.

As shown in FIG. 1, the basket reception part 50 includes a square frame-shaped frame 51 and the reception unit 52 provided on the lower side of the frame 51. The reception unit 52 is formed in the dimension in which the lower part of the shopping basket is housed. The frame 51 includes a horizontal frame 53 on the rear side. The flap plate 54 is attached to the horizontal frame 53 so as to freely swing around the horizontal frame 53.

The electrical device 100 includes a battery 110 and a product registration device 120. The battery 110 is disposed below the rear end of the basket reception part 50. Specifically, the battery 110 is attached across the vertical frames 41 and 41 in the middle part of the frame part 40. The product registration device 120 is attached to the upper end (upper end portion in the vertical direction) of the extension arm 43. The battery 110 supplies power to the product registration device 120 via a power line inserted into the extension arm 43. In this way, the shopping cart 10 operates as a registration device that reads the product code of a product that a shopper desires to purchase and moves by being pushed by the shopper.

The product registration device 120 includes the hand scanner (acquisition device) 130 that reads a product code and the tablet case 140. A tablet terminal 150 is provided inside the tablet case 140. On the surface of the tablet case 140, the scanner holder (holding part) 160 that detachably holds the hand scanner 130 is provided.

As shown in FIG. 2, the hand scanner 130 includes a head 131 and a handle 132 integrally provided to the lower part on the rear side of the head 131. As shown in FIG. 6, the head 131 includes an information acquisition unit 131 a that is provided on one side (on the front side) of a first direction and is to be directed to a product in order to acquire product information of the product. The head 131 has a predetermined width (hereinafter, referred to as first predetermined width) in a second direction orthogonal to the above-mentioned first direction, and is formed to have the first predetermined width on the rear side (on the different side of the first direction) narrower than the first predetermined width on the front side (on the one side of the first direction). More specifically, the head 131 is narrowed in the lateral direction (width direction) generally from the front side to the rear side as viewed from above in the vertical direction. Further, as shown in FIG. 4, the head 131 has such a shape that a central portion is wider in the width direction and an upper part (part on the upper side) and a lower part (part on the lower side) in the height direction (vertical direction) are narrower as viewed from the front (rear side of the first direction). Further, as shown in FIG. 2 or FIG. 5, the head 131 includes the information acquisition unit 131 a that is provided on the front side (on the one side of the first direction) and acquires the product code (product information) of a product. The information acquisition unit 131 a is directed to the product to acquire the product code of the product. For example, as shown in FIG. 2 or FIG. 5, the head 131 includes a flat placement part 131 c on the lower side on the front side. For example, as shown in FIG. 6, the head 131 includes contact parts 131 d on both side surfaces on the rear side. Note that assumption is made that the maximum dimension in the width direction of the head 131 is W (see FIG. 6). Further, assumption is made that the dimension in the width direction of the head 131 between the contact parts 131 d is T (see FIG. 6).

As shown in FIG. 5, the handle 132 is provided on the lower part on the rear side (the different side of the first direction) of the head 131, and has a predetermined width (second predetermined width) in the second direction. The handle 132 is formed to have the second predetermined width narrower than the first predetermined width on the rear side (on the different side of the first direction) of the head 131. Further, the handle 132 includes a scanner trigger 133. The scanner trigger 133 is provided on the front side (on the front side of the first direction) of the handle 132. The scanner trigger 133 is operated to start the scanner operation (operation of acquiring product information) by the information acquisition unit 131 a. Note that assumption is made that the maximum dimension of the handle 132 in the lateral direction (width direction) is H (see FIG. 4).

The hand scanner 130 is connected to the tablet terminal 150 via, for example a curl cord 134 shown in FIG. 2 and a built-in cable 135 shown in FIG. 3. One end of the curl cord 134 is connected to the information acquisition unit 131 a of the head 131, and the other end thereof is connected to the built-in cable 135. The built-in cable 135 is housed in the tablet case 140 described below. The length of the curl cord 134 is set such that the hand scanner 130 does not reach the floor surface even in the case where the hand scanner 130 hangs on the shopping cart 10 by its own weight when the shopper drops the hand scanner 130. Further, the curl cord 134 can be extended by the shopper as necessary. For example, the length of the curl cord 134 is set such that the curl cord 134 reaches near the bottom surface of the shopping basket placed on the reception part 33 of the caster part 30 farthest from the scanner holder 160.

The hand scanner 130 reads the product code attached to a product taken out of a display shelf by the shopper. The product code is a unique code set for each product for individually identifying the product.

The tablet case 140 is formed in a thin box shape. As shown in FIG. 3, the tablet case 140 includes a case body 141 and the open/close lid 142. The case body 141 is fixed to the extension arm 43. The open/close lid 142 is openably/closably attached to the case body 141. The open/close lid 142 includes an opening part 143. As shown in FIG. 5, a front part 132 a of the handle 132 of the hand scanner 130 is in contact with a lower end edge 144 of the tablet case 140. For example, as shown in FIG. 2 or FIG. 4, an attachment part 145 is formed on the front surface of the tablet case 140. For example, as shown in FIG. 2 or FIG. 5, in the tablet case 140, a stopper (handle contact part) 146 is formed at the lower end edge 144 of the case body 141. The stopper 146 is in contact with the handle 132 of the hand scanner 130 while the hand scanner 130 is held by the scanner holder 160 to regulate the forward movement of the handle 132.

As shown in FIG. 3, the tablet terminal 150 includes a terminal casing 151. The terminal casing 151 is disposed close to the right side in the width direction of the case body 141 in FIG. 3. The terminal casing 151 includes a display panel 152. The display panel 152 displays various types of information such as the product name and the unit price of the product read by the hand scanner 130. The display panel 152 is disposed to face the opening part 143 of the tablet case 140. The display panel 152 is exposed to the outside through the opening part 143 of the tablet case 140. In FIG. 3, a terminal part 153 is provided on the left side surface in the width direction of the terminal casing 151. A controller 154 is provided inside the terminal casing 151. The controller 154 collectively controls the battery 110, the hand scanner 130, and the tablet terminal 150. The controller 154 acquires product information on the basis of the product code read by the hand scanner 130.

As shown in FIG. 2, the scanner holder 160 is provided on the terminal casing 151 of the tablet terminal 150. The scanner holder 160 includes a head support 161 and a pair of head regulators 162, and holds the hand scanner 130 in cooperation with the stopper 146 of the tablet case 140. Specifically, the scanner holder 160 that holds the hand scanner 130 includes the stopper 146. The head support 161 is attached to the attachment part 145 of the tablet case 140. The placement part 131 c of the head 131 is placed on the head support 161. The pair of head regulators 162 are provided to have a space described below. The head regulators 162 are engaged with a rear end side part 131 b of the head 131 to hold the head 131.

The head support 161 is formed by bending a plate-like member. For example, as shown in FIG. 2 or FIG. 5, the head support 161 includes a retaining part 161 a, an extending part 161 b, and a supporting part 161 c. The retaining part 161 a is attached to the attachment part 145. The extending part 161 b extends in a direction away from the attachment part 145 from the upper end (upper end part) in the vertical direction of the retaining part 161 a. The supporting part 161 c is folded back to the side of the attachment part 145 from the extending part 161 b. The supporting part 161 c is formed to have a horizontal surface or a surface having the rear part slightly higher than the front part. The supporting part 161 c makes surface contract with the placement part 131 c of the head 131.

The head regulators 162 are provided to have a space that is narrower than a maximum width W (see FIG. 6) of the first predetermined width of the head 131 and wider than a maximum width H (see FIG. 4 and FIG. 6) of the second predetermined width of the above-mentioned handle. The head regulators 162 are in contact with the side surface (rear end side part 131 b) on the rear side (on the different side of the first direction) of the above-mentioned head 131 held in the space to regulate the rearward movement. More specifically, for example, as shown in FIG. 2 or FIG. 5, the head regulators 162 includes a pair of arms 163. The pair of arms 163 are attached to the supporting part 161 c at the base end thereof. The arms 163 each include a base-end arm 163 a, a horizontal arm 163 b, and a regulation arm 163 c. The base-end arm 163 a is on the side of the base end of the arms 163, and is formed to extend in the upward direction (upward direction of the substantially vertical direction). The lower end (lower end part in the vertical direction) of the base-end arm 163 a is attached to, for example, the supporting part 161 c of the head support 161. The horizontal arm 163 b is formed to extend in the horizontal direction from the upper end of the base-end arm 163 a (upper end part in the vertical direction in the figure). The regulation arm 163 c is formed to extend in the downward direction (downward direction of the vertical direction in the figure) from the front end side of the horizontal arm 163 b. A member that applies a frictional force to the head 131 is attached to the regulation arm 163 c. More specifically, as the above-mentioned member that applies the frictional force, rubber tubes 164 that are non-slips for the contact parts 131 d of the head 131 are attached to the regulation arm 163 c. The rubber tubes 164 each have a predetermined length R in the vertical direction in the figure (see FIG. 4).

For example, as shown in FIG. 2 and FIG. 6, the pair of horizontal arm 163 b are disposed along the shape of the head 131 so that the distance between them is reduced as they away from the attachment part 145 of the tablet case 140. Further, a dimension Q of the distance (distance in the width direction in FIG. 4) between the pair of rubber tubes 164 described above is substantially the same as a width dimension T (see FIG. 6) between the contact parts 131 d of the head 131 described above. Further, the dimension Q of the distance between the rubber tubes 164 is set to be narrower than the maximum width W (see FIG. 6) in the width direction of the head 131 and wider than the maximum width H (see FIG. 4 or FIG. 6) in the lateral direction of the handle 132.

Therefore, when the placement part 131 c of the head 131 is placed on the supporting part 161 c of the scanner holder 160 while the information acquisition unit 131 a of the tablet case 140 is directed forward, the contact parts 131 d of the head 131 on both sides are in contact with the inside of the pair of rubber tubes 164. Since the dimension of the head 131 in the width direction on the front side is larger than the dimension in the width direction on the rear side, movement from the rubber tubes 164 to the rear side is regulated.

The coefficient of friction and the dimension R of the rubber tubes 164 are set to such values that the shopper is capable of easily taking the hand scanner 130 from the scanner holder 160. Further, the coefficient of friction and the dimension R of the rubber tubes 164 are set to such values that the hand scanner 130 does not come out of the scanner holder 160 by vibration at the time when the shopping cart 10 travels.

Using the shopping cart 10 configured as described above, the shopper performs shopping as follows. Specifically, the shopping cart 10 is initially placed at the entrance or the like of a store. At this time, the hand scanner 130 is held by the scanner holder 160 of the shopping cart 10 so that the handle 132 is directed below. The placement part 131 c of the head 131 of the hand scanner 130 is placed on the supporting part 161 c of the scanner holder 160. The pair of contact parts 131 d of the head 131 on both sides are respectively in contact with the pair of rubber tubes 164 of the head regulators 162.

The shopper withdraws the shopping cart 10 in the stacking state in FIG. 7 to be used. Further, the shopper takes a shopping basket placed in the store, and places the shopping basket on at least one of the reception part 33 or the basket reception part 50 of the caster part 30. Then, while pushing the handle bar 42 of the shopping cart 10, the shopper moves the shopping cart 10 toward a product shelf where products of the store are displayed.

The shopper takes a target product from the product shelf. Further, the shopper takes the hand scanner 130 from the scanner holder 160. The shopper brings the product code of the taken-out product close to the head 131 of the hand scanner 130, and presses the scanner trigger 133. As a result, the product code is read by the hand scanner 130. The information regarding the read product code is transmitted to the controller 154. The controller 154 displays the product name, the price, and the like on the display panel 152 on the basis of the information regarding the product code. The shopper places the product whose product code has been read by using the hand scanner 130 in the shopping basket placed on any one of the reception part 33 or the basket reception part 50 of the caster part 30.

In this way, after reading (scanning) the product code of the product by using the hand scanner 130, while holding the handle 132, the shopper inserts the hand scanner 130 between the pair of arms 163 (head regulators 162) of the scanner holder 160 from above (upward in the vertical direction) so that the head 131 is directed upward (upward in the vertical direction). In the handle 132, the maximum width H in the width direction is narrower than the dimension Q of the distance between the rubber tubes 164 of the head regulators 162. Therefore, the shopper is capable of passing the handle 132 of the hand scanner 130 between the pair of rubber tubes 164. Therefore, the shopper is capable of placing the head 131 on the supporting part 161 c of the scanner holder 160 while holding the handle 132 of the hand scanner 130. Specifically, there is no need for the shopper to replace the handle 132 of the hand scanner 130 with the head 131. The hand scanner 130 is held by the scanner holder 160 so that the handle 132 is directed below. At this time, the placement part 131 c of the head 131 of the hand scanner 130 is placed on the head support 161 (supporting part 161 c) of the scanner holder 160. When the head 131 of the hand scanner 130 is placed on the head support 161, the head regulators 162 of the scanner holder 160 are in contact with the contact parts 131 d of the head 131 of the hand scanner 130. The shopper pulls the hand scanner 130 upward from the scanner holder 160 and takes it when using the hand scanner 130. Then, after using the hand scanner 130, the shopper is capable of causing the hand scanner 130 to be stably held by the shopping cart 10, only by inserting the hand scanner 130 into the scanner holder 160 from above (upward in the vertical direction). Specifically, in the shopping cart 10, the usability of the hand scanner 130 is excellent.

For example, the shopper moves the shopping cart 10 to move to the next product shelf. At this time, vibration is generated in the up-and-down direction (vertical direction), in the right and left direction (second direction), and the front-rear direction (first direction) in the scanner holder 160. Since the head 131 of the hand scanner 130 is supported by the head support 161 in the up-and-down direction (vertical direction), it does not drop out of the scanner holder 160. Further, since the head 131 of the hand scanner 130 is held in the right and left direction (second direction) and the front-rear direction (first direction) by the head regulators 162, it does not drop out of the scanner holder 160.

When all the shopping is done, the shopper goes to a payment device. Then, the shopper performs an operation for payment of the shopping product on the display panel 152 of the tablet terminal 150. When receiving the operation for payment by the shopper via the display panel 152, the controller 154 transmits a shopping list to the payment device. The shopper uses the payment device to make payment. The shopper who has finished the payment returns the shopping cart 10 to a predetermined position of the store.

In the case where the shopper stacks the shopping cart 10 for return, if he/she strongly pushes the shopping cart 10 into the forward shopping cart 10, an upward (upward in the vertical direction) force from the forward shopping cart 10 is applied to the hand scanner 130. Further, similarly, in the case where a store clerk gathers and stacks the used shopping carts 10, if he/she strongly pushes the shopping cart 10 into the forward shopping cart 10, an upward (upward in the vertical direction) force from the forward shopping cart 10 is applied to the hand scanner 130. The scanner holder 160 reduces the force of the hand scanner 130 to jump out by the frictional force by the rubber tube 164, which makes it possible to prevent the hand scanner 130 from falling off.

As described above, according to this embodiment, even in the case where the hand scanner 130 receives vibration when the shopping cart 10 travels or impact when stacking the shopping cart 10, the hand scanner 130 does not easily come out of the scanner holder 160. Therefore, it is possible to prevent the hand scanner 130 from being damages in advance, the shopper is capable of easily attach and detach the hand scanner 130, and the usability of the hand scanner 130 is improved.

Further, the head regulators 162 of the scanner holder 160 each include the regulation arm 163 c formed to be directed below in the vertical direction. Therefore, even in the case where an upward force in the vertical direction is applied to the head 131 of the hand scanner 130, the hand scanner 130 does not easily fall off. Further, the head regulators 162 each include the regulation arm 163 c formed to be directed below in the vertical direction. Therefore, the head regulators 162 do not easily fall off even in the case where an upward (upward in the vertical direction) is applied to the head 131. Further, since the rubber tubes 164 are attached to the regulation arms 163 c, friction occurs between the rubber tubes 164 with the contact parts 131 d of the head 131. Therefore, even in the case where an upward (upward in the vertical direction) force is applied to the head 131, the hand scanner 130 does not easily fall off and vibration applied to the head 131 is absorbed.

The stopper 146 of the tablet case 140 is in contact with the front surface side (on the one side of the first direction) of the handle 132 of the hand scanner 130 while the head 131 is held in the space of the head regulators 162 (see, for example, FIG. 5). The stopper 146 is in contact with the front surface side of the handle 132 to regulate the forward (one side of the first direction) movement of the handle 132. Therefore, the position of the handle 132 is stabilized. Further, in an embodiment, the stopper 146 is formed of a member different from that of the lower end edge of the case body 141 of the tablet case 140. Meanwhile, by using the stopper 146 as the lower end edge of the tablet case 140, the structure can be simplified without the need for additional members.

Further, the tablet case 140 can be attached or moved to another shopping cart that does not include the electrical device 100. Also in this case, by the scanner holder 160 provided on the tablet case 140, it is possible to prevent the hand scanner 130 from falling off.

In the above-mentioned embodiment, in the tablet case 140, the position of the attachment part 145 of the scanner holder 160 is on the left side of the display panel 152, but may be on the right side of the display panel 152. Further, the scanner holder 160 may be attached at a position different from the tablet case 140. Further, instead of providing the rubber tubes 164 of the head regulators 162, anti-slip processing may be performed on the surface of the regulation arm 163 c.
